N2 - Due to the limited resources of the embedded mobile computing systems, such as wearable computers, PDAs or sensor nodes, reducing the overhead of the software implemented fault tolerance mechanism is a key factor in reliability design. Two checkpoint interval optimization techniques of kernel-level rollback recover mechanism are discussed. Step-checkpointing algorithm modulates checkpoint intervals on-line according to the characteristics of software or hardware environment-dependent system that the failure rate fluctuates acutely shortly after the system fails. Checkpoint size monitoring and threshold-control technique adjusts the checkpoint interval by predicting the amount of data to be saved. Combining these two techniques can effectively improve the performance of the embedded mobile computer system.
